9196 Sukagawa           Discovered 1992 Nov. 27 by T. Seki at Geisei.
In the city of Sukagawa, Fukushima prefecture, there exists the best peony garden in the world. The city also hosts "Taimatsuakashi", one of the three large Japanese fire festivals. Sukagawa is the hometown of marathon runner Kokichi Tsuburaya and movie producer Eiji Tsuburaya. The name was suggested by H. Sato.
